Embodiment Construction
[0007] When hot water is used in the bathroom, the waste hot water flows into the first-level pipeline for heat neutralization, then enters the second-level pipeline for heat neutralization with waste hot water, and then enters the third-level and fourth-level pipelines for heat neutralization, thereby achieving high heat for recycling purposes.
[0008] In practice, when the invention is applied in bathing, 30% of heat can be recovered and energy saving can be achieved.

Description
technical field [0001] The invention relates to a heat recovery method, in particular to a waste hot water recovery method. Background technique [0002] In the bathroom, especially in winter, a lot of hot water is used, and the used hot water is directly discharged into the sewer through pipes, and the used hot waste water takes away a lot of heat, resulting in waste of heat energy. Contents of the invention [0003] Aiming at the defects of the prior art, the invention provides a heat recovery device for waste hot water in a bathroom. [0004] In order to achieve the above object, the present invention takes the following measures to achieve: [0005] A multi-stage heat recovery system, including waste hot water and pipes, is characterized in that multi-stage circulating water pipes are arranged, and multiple heat neutralizations are performed through layered heat collection, so as to achieve a method of recovering high heat. [0006] Compared with the prior art, the p...
